I purchased the light blue/bright yellow version of this shirt and I just want to throw it out there that it does not look like the photo. It's (as other people have mentioned) a translucent mesh fabric. The back is super see-through. Also, there is no Brooks logo on the back inside/outside of the shirt like there is in the photo. Fits a little big.

I have 2 of these D'Lite Tanks: 1 reversible and the other has the pink floral pattern. I am usually a medium in all of Brooks apparel, however the medium was was huge, particularly in the arm holes. The small fits perfect. It is perfect for really hot & muggy days if you don't mind the transparency of the tank.
